The Controversial Cec Pepper and the Australian Services Cricket Team: The Test Career That Never Was

The Australian Services cricket teams of both WWI and WWII played an important role in the immediate post-war period. A number of the players involved went on to forge successful Test cricket careers. This paper mentions the exploits of some of the players involved in these matches with particular focus on Cecil (Cec) Pepper. Cec Pepper represented the WWII Australian Services Team with distinction during the exhausting schedule of matches played in England, India and Australia from June 1945. However, in the match between the Australian Services Team and South Australia played at the Adelaide Oval over the Christmas–New Year period of 1945/1946, Pepper was involved in a controversial incident with the South Australian captain Donald Bradman and umpire Jack Scott. The incident and its subsequent ramifications were to have a huge impact on Pepper's cricket career. Pepper should have been in contention as a future Australian Test player. Instead, his career took another direction completely. This paper discusses Pepper's career and traces further links between the three Adelaide protagonists, Bradman, Scott and Pepper. A comparison is also made between Cec Pepper and other Australian spin bowlers of the era.

Effects of the differences between native and non-native English-speaking teachers on students’ attitudes and motivation toward learning English

This study presents findings on three research agendas: (1) the difference between native English-speaking teachers (NESTs) and non-native English-speaking teachers (NNESTs) in students’ attitudes toward and motivation for learning English, (2) the moderating effect of the type of class (i.e., English Conversation vs. Practical English) on the difference in students’ perceived attitudes and motivation, and (3) the difference between NESTs and NNESTs in their self-perception of their teaching practices and the effect of the type of class on this difference. The results indicate significant differences between NESTs and NNESTs in terms of their students’ perceived attitudes and motivation with respect to English learning. However, these differences varied depending upon the type of class. These results provide empirical support for the role of the type of class as a variable moderating the effect of the difference between NESTs and NNESTs on students’ attitudes and motivation. In addition, the type of class moderated teachers’ self-perception of their own teaching practices, providing support for the moderating effect of the type of class on various measures and samples. Theoretical as well as pedagogical implications are discussed.     

中国西北沙漠对东亚大气粉尘影响的数值试验研究

以塔克拉玛干沙漠为主的中国西北沙漠区是东亚地区主要沙尘释放源区之一。本文利用美国大气研究中心（NCAR）的公用气候模式（CCM3）与一个沙尘释放和沉降模式（DEAD）相嵌套、能够反映沙尘扬起及输送和沉降动态过程的耦合模式系统（CCM3-DEAD），通过改变中国西北沙漠-半沙漠区下垫面类型的数值模拟试验，对比分析了西北沙尘源区地表类型的改善对东亚地区沙尘释放及大气粉尘含量变化的可能影响。研究结果表明，地表覆盖状况与沙尘释放关系密切，沙尘源区地表类型的改善可明显抑制沙尘的释放。中国西北沙漠-半沙漠区地表的改善，可引起整个中国北方至蒙古国的大气粉尘含量减少，使大气环境明显改善。假设以塔克拉玛干为主的沙漠-半沙漠区不存在（当地地表类型若以温带草原植被为主），则整个中国北方沙尘释放和沉降通量仅为目前的50%左右。模式中分4个粒级描述沙尘释放及沉降通量，其中1.0~2.5μm和2.5~5.0μm两个粒级的贡献约占总通量的76%，对比试验显示在没有塔克拉玛干等沙漠存在的情况下这两个粒径释放通量大大降低。由西北沙漠-半沙漠区释放的沙尘，经大气环流传输可直接影响到我国东北、华北等东部地区的大气粉尘状况，并对日本、韩国及其周边地区也有一定影响。
